Abstract

The CaNaPy project pioneers a novel configuration in Visible Wavelength Laser Guide Star Adaptive Optics (LGS-AO). Collaboratively established by ESA and ESO, it hosts a 70 W CW 589nm laser, employing upward propagation pre-compensation on sodium LGS via a pyramid wavefront sensor (Py-WFS). Operating at Teide Observatory, its aim is to demonstrate the benefits of pre-compensating the LGS upward propagation path, reducing LGS spot size in the mesosphere. This enhances Sodium optical pumping effects and significantly boosts Py-WFS sensitivity. Early on-sky experiments, using Natural Guide Stars, are underway, comparing results with simulation predictions using PASSATA. These trials mark a critical milestone in advancing visible wavelength LGS-AO, promising better resolution and sensitivity with reduced laser power requirements.
